The present inventor has carried out in vitro assays and have measured the activity of the present compounds on the inhibition of LPS-induced nitric oxide and TNFα secretion from murine macrophage cells. The inventors have found, surprisingly and unexpectedly that NO and TNFα activity can be resolved, and it is possible to dissect apart the NO and TNFα activity with compounds having potency in an NO assay which are relatively inactive for TNFα. The inventors have also found that it is possible to provide good “mixed” inhibitors and also more selective TNFα inhibitors. Both TNF activity as well as possible biological targets are contemplated herein.

In particular, the compounds herein are particularly useful for administration to a subject, preferably human, to prevent or reduce the generation of nitric oxide (NO) or in anti-TNF alpha therapy, or to treat or prevent any condition or disease mediated by either or both of NO and TNF alpha. In one embodiment, the compounds may be symmetrical, i.e., have the same groups on either side of the Z linker. In another embodiment, the compounds may be asymmetrical, i.e., have different groups on either side of the linker. In this regard, the linker Z itself is not included in the calculus of symmetry/asymmetry, e.g., a compound having an asymmetrical linker group Z connected to symmetrical end groups would be a symmetrical compound. In one embodiment, a mixture of symmetrical and asymmetrical compounds may be administered. In one embodiment, both asymmetrical and symmetrical compounds are suitable for administration to a subject, preferably human, to prevent or reduce the generation of nitric oxide (NO) or in anti-TNF alpha therapy, or to treat or prevent any condition or disease mediated by either or both of NO and TNF alpha. In another embodiment, asymmetrical compounds exhibit more pronounced anti-TNF alpha activity. In another embodiment, the symmetrical compounds exhibit more pronounced anti-NO activity.

The compounds herein are basic and may if desired form pharmaceutically acceptable salts with organic and inorganic acids. Nonlimiting examples of suitable acids for such acid addition salt formation are hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, acetic acid, citric acid, oxalic acid, malonic acid, salicylic acid, p-aminosalicylic acid, malic acid, fumaric acid, succinic acid, ascorbic acid, maleic acid, sulfonic acid, phosphonic acid, perchloric acid, nitric acid, formic acid, propionic acid, gluconic acid, lactic acid, tartaric acid, hydroxymaleic acid, pyruvic acid, phenylacetic acid, benzoic acid, p-aminobenzoic acid, p-hydroxybenzoic acid, methanesulfonic acid, ethanesulfonic acid, nitrous acid, hydroxyethanesulfonic acid, ethylenesulfonic acid, p-toluenesulfonic acid, naphthylsulfonic acid, sulfanilic acid, camphersulfonic acid, china acid, mandelic acid, o-methylmandelic acid, hydrogen-benzenesulfonic acid, picric acid, adipic acid, d-o-tolyltartraric acid, tartronic acid, α-toluic acid, (o, m, p)-toluic acid, naphthylamine sulfonic acid, and other mineral or carboxylic acids well known to those skilled in the art.

In one embodiment, the compound is in the form of mucate, isethionate, acetate, glutamate, L-lactate, L-tartrate, tosylate, mesylate, fumarate, maleate, citrate, sulfate and combinations thereof. Compositions containing mixtures of salts are possible.

The free base forms may be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous sodium hydroxide, potassium carbonate, ammonia and sodium bicarbonate. The free base forms differ from their corresponding salt forms somewhat in certain physical properties, such as solubility in polar solvents, but the salts are otherwise equivalent to their corresponding free base forms.

One embodiment relates to pharmaceutical compositions comprising at least one compound and/or pharmaceutically acceptable salt thereof as an active ingredient and a pharmaceutically acceptable carrier, excipient, adjuvant and/or diluent.

The compounds can also be administered in a form of their pharmaceutically active salts optionally using substantially nontoxic pharmaceutically acceptable carriers, excipients, adjuvants or diluents. The compositions may be prepared in any conventional solid or liquid carrier or diluent and optionally any conventional pharmaceutically-made adjuvant at suitable dosage level in a known way. The preferred preparations are in administrable form which is suitable for oral application. These administrable forms, for example, include pills, tablets, film tablets, coated tablets, capsules, powders and deposits.

Forms other than orally administrable forms are also possible. The compounds and/or pharmaceutical preparations containing said compounds may be administered by any appropriate means, including but not limited to injection (intravenous, intraperitoneal, intramuscular, subcutaneous) by absorption through epithelial or mucocutaneous linings (oral mucosa, rectal and vaginal epithelial linings, nasopharyngial mucosa, intestinal mucosa); orally, rectally, transdermally, topically, intradermally, intragastrally, intracutanly, intravaginally, intravasally, intranasally, intrabuccally, percutanly, sublingually, or any other means available within the pharmaceutical arts.

The pharmaceutical compositions, containing at least one compound and/or pharmaceutically acceptable salts thereof as an active ingredient, will typically be administered in admixture with suitable carrier materials suitably selected with respect to the intended form of administration, i.e. oral tablets, capsules (either solid-filled, semi-solid filled or liquid filled), powders for constitution, oral gels, elixirs, dispersible granules, syrups, suspensions, and the like, and consistent with conventional pharmaceutical practices. For example, for oral administration in the form of tablets or capsules, the active drug component may be combined with any oral nontoxic pharmaceutically acceptable inert carrier, such as lactose, starch, sucrose, cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, talc, mannitol, ethyl alcohol (liquid forms) and the like. Moreover, when desired or needed, suitable binders, lubricants, disintegrating agents and coloring agents may also be incorporated in the mixture. Powders and tablets may be comprised of from about 5 to about 95 percent by weight of the inventive compound, salt thereof, or a mixture of compound and salt, which range includes all values and subranges therebetween, including 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, and 90% by weight.

Among the lubricants there may be mentioned for use in these dosage forms, boric acid, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrants include starch, methylcellulose, guar gum and the like. Sweetening and flavoring agents and preservatives may also be included where appropriate. Some of the terms noted above, namely disintegrants, diluents, lubricants, binders and the like, are discussed in more detail below.

Additionally, the compounds or compositions may be formulated in sustained release form to provide the rate controlled release of any one or more of the components or active ingredients to optimize the therapeutic effects, i.e. antihistaminic activity and the like. Suitable dosage forms for sustained release include layered tablets containing layers of various disintegration rates or controlled release polymeric matrices impregnated with the active components and shaped in tablet form or capsules containing such impregnated or encapsulated porous polymeric matrices.

Liquid form preparations include solutions, suspensions and emulsions. Nonlimiting examples include water, ethanol, ethanolic, water-ethanol or water-propylene glycol solutions for parenteral injections or addition of sweeteners and opacifiers for oral solutions, suspensions and emulsions. Liquid form preparations may also include solutions for intranasal administration.

Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier such as inert compressed gas, e.g. nitrogen.

For preparing suppositories, a low melting wax such as a mixture of fatty acid glycerides such as cocoa butter is first melted, and the active ingredient is dispersed homogeneously therein by stirring or similar mixing. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool and thereby solidify.

Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions.

The compounds may also be deliverable transdermally. The transdermal compositions may take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose.

The term capsule refers to a special container or enclosure made of methyl cellulose, polyvinyl alcohols, or denatured gelatins or starch for holding or containing compositions comprising the active ingredients. Hard shell capsules are typically made of blends of relatively high gel strength bone and pork skin gelatins. The capsule itself may contain small amounts of dyes, opaquing agents, plasticizers and preservatives.

Tablet means compressed or molded solid dosage form containing the active ingredients with suitable diluents. The tablet can be prepared by compression of mixtures or granulations obtained by wet granulation, dry granulation or by compaction well known to a person skilled in the art.

Oral gels refers to the active ingredients dispersed or solubilized in a hydrophillic semi-solid matrix.

Powders for constitution refers to powder blends containing the active ingredients and suitable diluents which can be suspended in water or juices.

Suitable diluents are substances that usually make up the major portion of the composition or dosage form.

Suitable diluents include sugars such as lactose, sucrose, mannitol and sorbitol, starches derived from wheat, corn rice and potato, and celluloses such as microcrystalline cellulose. The amount of diluent in the composition can range from about 5 to about 95% by weight of the total composition, preferably from about 25 to about 75%, more preferably from about 30 to about 60% by weight.

The term disintegrants refers to materials added to the composition to help it break apart (disintegrate) and release the medicaments. Suitable disintegrants include starches, “cold water soluble” modified starches such as sodium carboxymethyl starch, natural and synthetic gums such as locust bean, karaya, guar, tragacanth and agar, cellulose derivatives such as methylcellulose and sodium carboxymethylcellulose, microcrystalline celluloses and cross-linked microcrystalline celluloses such as sodium croscarmellose, alginates such as alginic acid and sodium alginate, clays such as bentonites, and effervescent mixtures. The amount of disintegrant in the composition can range from about 2 to about 20% by weight of the composition, more preferably from about 5 to about 10% by weight.

Binders characterize substances that bind or “glue” powders together and make them cohesive by forming granules, thus serving as the “adhesive” in the formulation. Binders add cohesive strength already available in the diluent or bulking agent. Suitable binders include sugars such as sucrose, starches derived from wheat, corn rice and potato; natural gums such as acacia, gelatin and tragacanth; derivatives of seaweed such as alginic acid, sodium alginate and ammonium calcium alginate; cellulosic materials such as methylcellulose and sodium carboxymethylcellulose and hydroxypropyl-methylcellulose; polyvinylpyrrolidone; and inorganics such as magnesium aluminum silicate. The amount of binder in the composition can range from about 2 to about 20% by weight of the composition, more preferably from about 3 to about 10% by weight, even more preferably from about 3 to about 6% by weight.

Lubricant refers to a substance added to the dosage form to enable the tablet, granules, etc. after it has been compressed, to release from the mold or die by reducing friction or wear. Suitable lubricants include metallic stearates such as magnesium stearate, calcium stearate or potassium stearate; stearic acid; high melting point waxes; and water soluble lubricants such as sodium chloride, sodium benzoate, sodium acetate, sodium oleate, polyethylene glycols and d,l-leucine. Lubricants are usually added at the very last step before compression, since they must be present on the surfaces of the granules and in between them and the parts of the tablet press. The amount of lubricant in the composition can range from about 0.2 to about 5% by weight of the composition, preferably from about 0.5 to about 2%, more preferably from about 0.3 to about 1.5% by weight.

Glidents are materials that prevent caking and improve the flow characteristics of granulations, so that flow is smooth and uniform. Suitable glidents include silicon dioxide and talc. The amount of glident in the composition can range from about 0.1% to about 5% by weight of the total composition, preferably from about 0.5 to about 2% by weight.

Coloring agents are excipients that provide coloration to the composition or the dosage form. Such excipients can include food grade dyes and food grade dyes adsorbed onto a suitable adsorbent such as clay or aluminum oxide. The amount of the coloring agent can vary from about 0.1 to about 5% by weight of the composition, preferably from about 0.1 to about 1%.

Techniques for the formulation and administration of the compounds may be found in “Remington's Pharmaceutical Sciences” Mack Publishing Co., Easton Pa., the entire contents of which are hereby incorporated by reference. A suitable composition comprising at least one compound of the invention may be a solution of the compound in a suitable liquid pharmaceutical carrier or any other formulation such as tablets, pills, film tablets, coated tablets, dragees, capsules, powders and deposits, gels, syrups, slurries, suspensions, emulsions, and the like.

The term “treating” as used herein refers to reversing, alleviating, inhibiting the progress of, or preventing the disorder or condition to which the term applies, or one or more symptoms of the disorder or condition. The term “treatment” as used herein refers to the act of treating as the term is defined above.

The compounds can exist in several tautomeric forms, and geometric isomers and mixtures thereof. All such tautomeric forms are included within the scope of the present invention. Tautomers exist as mixtures of tautomers in solution. In solid form, usually one tautomer predominates. Even though one tautomer may be described, the present invention includes all tautomers of the present compounds.

The present invention also includes atropisomers. Atropisomers refer to compounds that can be separated into rotationally restricted isomers. These compounds may contain olefin-like double bonds. When such bonds are present, the compounds exist as cis and trans configurations and as mixtures thereof.

The compound may exist in any convenient crystalline, semicrystalline, or amorphous form. These may be achieved via typical crystallization routes including vacuum crystallization or spray drying. Depending on the solubility desired, the amorphous form obtained by, e.g., spray-drying may be preferred. The spray drying may be carried out from aqueous, ethanolic, organic, or mixed aqueous ethanolic solutions of the compound or its salt or a mixture thereof. The compound may exist in a form comprising one or more waters of hydration.

The present invention also includes isotopically-labeled acid compounds, which are identical to those recited above, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³¹P, ³²P, ³⁵S, ¹⁸F, and ³⁶Cl, respectively. Compounds, prodrugs thereof, and pharmaceutically acceptable salts of said compounds or of said prodrugs which contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of this invention. Certain isotopically-labeled compounds, for example, those into which radioactive isotopes such as ³H and ¹⁴C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i.e., ³H, and carbon-14, i.e., ¹⁴C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium, i.e., ²H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, it would be preferred in some circumstances. Isotopically labeled compounds and/or prodrugs can generally be prepared by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.

After stirring for 15 minutes, the ice bath was removed and the reaction mixture was stirred at room temperature for 15 hours. Water was then added and the mixture was filtered. The solid was collected and boiled in a 1/1 mixture of acetone/methanol (30 mL). After cooling the mixture to room temperature, the mixture was filtered again and the solid was collected. The off-white solid was very clean diamide product (142 mg, 0.305 mmol). LC/MS (EI) 465 (M+1), 487 (M+Na).

The diamide (142 mg, 0.306 mmol) was suspended in 4 mL of 2-methoxyethanol. Concentrated HCl (27 μL, 0.43 mmol) and 1.3 mL of water were added and the mixture was heated to 50° C. Aminoguanidine hydrochloride (68 mg, 0.62 mmol) was added and the mixture was stirred at 60° C. for four hours. Ethanol (2 mL) was added and the reaction was stirred at room temperature for two days.

After eight hours, the reaction mixture became a clear solution. Another 289 mg of the aminoguanidine hydrochloride was added and the mixture stirred at 115° C. for 15 hours. A white precipitate was now visible. The reaction mixture was cooled to room temperature and filtered. The solids were washed with 20 mL of water, collected and dried. Recrystallization from 25 mL of methanol gave the product as a white solid (145 mg, 50%): ¹H NMR (DMSOd⁶) δ 11.04 (s, 4H), 10.14 (s, 2H), 8.10 (s, 4H), 8.05 (s, 2H), 7.75 (broad s, 12H), 2.36 (m, 16H), 1.62 (broad s, 4H), 1.35 (broad s, 4H); LC/MS (EI) 717 (M+1), 739 (M+Na).

2,5-Thiophenedicarboxylic acid (200 mg, 1.16 mmol) was suspended in 4 mL of methylene chloride. Oxalyl chloride (0.25 mL, 2.9 mmol) was added. One drop of dimethylformamide was then added. The evolution of gas was observed. After 20 minutes, it had stopped and another drop of dimethylformamide was added. This was repeated for one hour. The solvent was removed from the reaction mixture and the yellow solid was dried by a vacuum pump. The diacid chloride was used without further purification.

The addition was repeated and the stirring was continued for 18 hours. The reaction mixture was cooled to room temperature. The mixture was filtered and the solids were washed with 20 mL of water. The solid was collected and triturated with methylene chloride. Further purification was accomplished by recrystallization from 25 mL of boiling ethanol and gave the product as a beige solid (179 mg, 63%): ¹H NMR (DMSOd^(d)) δ 11.05 (s, 4H), 10.79 (s, 2H), 8.37 (s, 4H), 8.28 (s, 2H), 8.12 (s, 2H), 2.41 (s, 12H); LC/MS (EI) 715 (M+1); 737 (M+Na).

Sebacic acid monomethyl ester (238 mg, 1.10 mmol) was suspended in 4 mL of methylene chloride. Oxalyl chloride (0.12 mL, 1.3 mmol) was added. One drop of dimethylformamide was then added. The evolution of gas was observed. After 20 minutes, it had stopped and another drop of dimethylformamide was added. This was repeated for one hour. The solvent was removed from the reaction mixture and the yellow solid was dried by a vacuum pump. The acid chloride was used without further purification.

3,5-Diacetylaniline (133 mg, 0.750 mmol) and pyridine (0.21 mL, 1.5 mmol) were combined in 5 mL of methylene chloride. The acid chloride (194 mg, 0.825 mmol) in 3 mL of methylene chloride was slowly added. The reaction mixture was stirred at room temperature for 5 hours. An aqueous, saturated solution of sodium bicarbonate was added and the mixture continued stirring for 30 minutes. The two phases were separated and the aqueous solution was extracted with methylene chloride. The organics were combined and dried over sodium sulfate. The product was purified by column chromatography using 3:1 methylene chloride:ethyl acetate as the eluent. This gave 210 mg (75%) of the desired product as an off-white solid: LC/MS (EI) 376 (M+1).

The monomethyl ester amide (210 mg, 0.559 mmol) was dissolved in a 3:1 mixture of methanol:water. Lithium hydroxide monohydrate (47 mg, 1.1 mmol) was added and the reaction mixture was stirred for one day. The methanol was removed by rotary evaporation. The residue was diluted with 30 mL of water and was extracted three times with 20 mL of ethyl acetate. The aqueous layer was acidified to a pH˜2 using 1 mL of 6N hydrochloric acid solution. The aqueous layer was then extracted again three times with 20 mL of ethyl acetate. The organics from this last extraction were combined and dried over sodium sulfate. The mixture was then filtered and the solvent removed by rotary evaporation. The residue was purified by trituration with methylene chloride to give the pure product as a white solid (121 mg, 61%): ¹H NMR (DMSOd⁶) δ 10.28 (s, 1H), 8.42 (s, 2H), 8.14 (s, 1H), 2.63 (s, 6H), 2.34 (t, J=7.6 Hz, 2H), 2.18 (t, J=7.3 Hz, 2H), 1.60 (m, 2H), 1.49 (m, 2H), 1.28 (m, 8H); LC/MS (EI) 715 (M+1); 737 (M+Na).

The diamide (149 mg, 0.341 mmol) was suspended in 10 mL of 2-methoxyethanol. The aminoguanidine hydrochloride (113 mg, 1.02 mmol) was added and the mixture was heated to 95° C. for 8 hours. More aminoguanidine hydrochloride (113 mg, 1.02 mmol) was added and the reaction mixture continued to be stirred at 95° to 100° C. for another 15 hours. Conversion was still not complete and aminoguanidine hydrochloride (226 mg, 2.04 mmol) was added again and the temperature was raised to 120° C. and heated for 8 hours. The addition was repeated the mixture was stirred another 15 hours at that temperature. The mixture was then cooled to room temperature and the solvent was removed by rotary evaporation. The residue was heated with 25 mL of methanol until it dissolved completely. A small amount of water (1 mL) was added and the mixture was cooled to room temperature. The crystals that formed were collected to give pure product (60 mg, 28%): ¹H NMR (DMSOd⁶) δ 11.29 (s, 2H), 10.16 (s, 1H), 9.91 (s, 1H), 8.72 (s, 1H), 8.12 (s, 2H), 8.04 (s, 1H), 7.84 (broad s, 6H), 7.59 (d, J=7.7 Hz, 2H), 7.27 (t, J=8.0 Hz, 2H), 7.00 (t, J=7.4 Hz, 1H), 4.69 (s, 1H), 2.38 (s, 6H), 2.31 (m, 4H), 1.59 (m, 4H), 1.30 (broad s, 8H); LC/MS (EI) 549 (M+1), 571 (M+Na).

3-Acetylaniline (201 mg, 1.49 mmol) and pyridine (0.18 mL, 1.7 mmol) were combined in 10 mL methylene chloride. Sebacoyl chloride (0.18 mL, 0.85 mmol) was slowly added and the reaction mixture was stirred at room temperature for 16 hours. A saturated aqueous solution of sodium bicarbonate (5 mL) was added and the mixture was stirred for 30 minutes. The mixture was filtered and the solids collected. This gave 310 mg (95%) of the product as a white solid: LC/MS (EI) 437 (M+1), 459 (M+Na).

The diamide (272 mg, 0.623 mmol) was suspended in 10 mL of 2-methoxyethanol. The aminoguanidine hydrochloride (207 mg, 1.87 mmol) was added and the mixture was heated to 115° C. and was stirred for 8 hours. More aminoguanidine hydrochloride (207 mg, 1.87 mmol) was added and the mixture continued to stir at 115° C. for one day. The mixture was then cooled to room temperature and the solvent was removed by rotary evaporation. The residue was dissolved in 8 mL of hot methanol and 1 mL of water was added. The mixture was allowed to slow cool to room temperature and set for 2 days. The mixture was filtered and the crystals were collected to give pure product (248 mg, 64%): ¹H NMR (DMSOd⁶) δ 10.98 (s, 2H), 10.00 (s, 2H), 7.98 (s, 2H), 7.72 (m, 8H), 7.33 (t, J=8.0 Hz, 2H), 3.30 (s, 2H), 2.30 (m, 10H), 1.59 (m, 4H), 1.30 (s, 8H); LC/MS (EI) 549 (M+1); 571 (M+Na).

Other Compounds:

30 mg of mono-aminoguanidine were prepared. From the method of synthesis and purification, this was probably the free base. The material was very high quality, on the order of 97-98% by HPLC. The NMR data was also clean.

Tetra-Aminoguanidine Compound:

The acid chloride route was chosen for these compounds, since there was less contamination with DCC by-products.

Tetra-Acetyl Compound:

Tris-Aminoguanidine Compound:

Using conditions similar to the mono-aminoguanidine synthesis, the tetra-acetyl compound was dissolved completely in CH₃CN:THF and a solution of amino-guanidinine hydrochloride in methanol was added. Only two equivalents of amino-guanidine were used, since the object was to make the bis-amino guanidine impurity. However, this reaction produced mono and tris amino-guanidine, with very little bis. The tris amino-guanidine precipitated from the reaction mixture along with some mono, resulting in a 3:1 mixture. Attempts to purify this by chromatography were not successful, but chromatography will be tried again. However, it may turn out that each compound behaves differently, and each will require a different purification scheme.

The following compounds were prepared.

Compounds: Analog 5 Analog 6 Analog 7 Analog 9 Analog 10 Analog 11 Analog 12 Analog 13 CNI-1493 Methods:

The studies were conducted in RAW 264.7 cultures.

Culture of RAW 264.7 Cells:

RAW 264.7 murine macrophage cells (ATCC, TIB-71) were maintained at 5% CO₂, 37° C. in RPMI media (Fisher 15-040-CV, 1 mg/L glutathione) with 10% fetal bovine serum (fbs, Fisher, lot 05069F) plus 2 mM L-glutamine and penicillin/streptomycin. The cells were subcultured every two to three days. Cells were plated in tissue culture treated 96 well plates at a density of 1×10⁵ cells/well and incubated at 5% CO₂, 37° C. for at least one hour prior to initiation of the assay.

The cells were washed with RPMI with 10% fbs prior to the initiation of the assay.

Anti-Inflammatory Activity:

The compounds were weighed, dissolved in DMSO for stock solutions of 10 mg/mL and serially diluted in RPMI. The plated RAW 264.7 cells were pretreated in duplicate with the test compounds, control (CNI-1493) or vehicle for 1 hour at final concentrations of 0, 0.1, 1.0, 10, and 100 μg/mL. The cells were stimulated with 100 ng/mL LPS (E. coli 0111:B4) and incubated at 5% CO₂, 37° C. for 24 hours. The media was collected and stored at −20° C.

TNFα Quantitation:

Murine TNFα was measured by ELISA (BioSource or comparable commercial source) following the suppliers instructions. The stored media was diluted 1:30.

Nitric Oxide (Nitrite) Measurement:

To 50 μL of cell-free media, 50 L of Griess Reagent (1 part 0.1% naphthylethylenediamine diHCl, 1 part 1.32% sulfanilimide in 60% acetic acid) was added and incubated for no more than 5 minutes at ambient temperature. The samples were read on a microtiter plate reader at 540 nm and compared to a 0.1-5 nmol nitrite standard curve.

Results and Discussion:

Four compounds, Analog 10, Analog 12, Analog 5 and Analog 11 inhibit release of TNFα from LPS-induced RAW 264.7 cells with IC₅₀ values of 8.8, 26.7, 27.7 and 47.6 g/mL, respectively (FIG. 1). CNI-1493 inhibits release of TNFα at an IC₅₀ of approximately 8 μg/mL. The remaining compounds have little (IC₅₀>50 μg/mL) or no (IC₅₀>100 μg/mL) effect on TNFα release.

Nitric oxide release is inhibited by CNI-1493 (FIG. 2) with an IC₅₀ of approximately 5.5 g/mL. Nitric oxide release is inhibited with IC₅₀ values of <1 μg/mL by Analog 5, Analog 12 and Analog 7 and to a lesser extent by the remaining compounds (FIG. 2).

FIGS. 3 and 4 show the combined results for inhibition of nitric oxide and TNFα release. No absolute correlation appears to exist between activity for nitric oxide inhibition and inhibition of TNFα release.

FIG. 5 shows structures and results of these and other compounds.

Analog 10, Analog 12, Analog 5 and Analog 11 inhibit release of TNFα from LPS-induced RAW 264.7 cells with IC₅₀ values of 8.8, 26.7, 27.7 and 47.6 μg/mL, respectively.

Analog 5, Analog 12 and Analog 7 inhibit nitric oxide release with IC₅₀ values of <1 μg/mL.

No absolute correlation appears to exist between activity for nitric oxide inhibition and inhibition of TNFα release.
